Draw the slide under 400X. Indicate the cell type, magnification, and estimate the cell size. 14. Elodea 1. Prepare a wet mount of an Elodea leaf (Anarcharis). You will use one glass slide and cover slip for this entire lab. After preparing each slide, remove the specimen and throw it into the trash. Wash the slide in the sink. Dry the slide with a paper towel very carefully and pat the cover slip dry so that the plastic does not...

1. Label the microphylls and strobili in the Figure 1 below. Figure 1. Lycopodium sp. Examine the prepared slide of a mature Lycopodium strobilus. (See text Figure 17-16, pages 406 and 407.) Note that Lycopodium, like most species in the Lycopodiaceae, is homosperous and only produces one type of spore 2. Label the spores in Figure 2 below. Figure 2. Lycopodium strobilus 1.s. 3. Given that Lycopodium is homosporaus, would you expect its gametophytes to be unisexual or bisexual? Explain...

In placing a sample on a microscope slide, a glass cover is placed over a water drop on the glass slide. Light incident from above can reflect from the top and bottom of the glass cover and from the glass slide below the water drop. At which surfaces will there be a phase change in the reflected light? Why? Explain using diagrams and calculations (if necessary).

Dense Irregular Connective Tissue 1 Examine a slide of thick skin under low power. In Activity 5.1, you observed the epidermis. Locate this layer again and identify the type of epithelium. 2 Directly below the epidermis is the dermis of the skin. The deep region of the dermis is composed of dense irregular connective tissue. This type of connective tissue consists mostly of collagen fibers, although elastic and reticular fibers are also present. How does the arrangement of the fibers...

The vertical drop of water in a hydroelectric power plant is 155m (See figure below). Water flows through the plant and into the lower river at the rate of 425m/s. Assume the overall efficiency of the plant as 80%. Density of water d is equal to 1000kg/m3 Acceleration due to gravity g is equal to 9.81m/s2. Ignore the viscous losses in the flowing water.
